11 Claims. (Cl. 72-115) This invention relates to building constructions, and has reference more particularly to a building construction utilizing specially constructed wire studs together with suitable accessories.

In the construction of walls, ceilings and partitions of a building, it has been customary to utilize steel studs of various constructions, such as that shown in patent to Balduf No. 2,087,867. I have found that a stud built up of wires suitably welded together, has somewhat greater strength and resistance to bending and twisting. Such a stud also lends itself well to assembly in a wall if proper accessories are provided.

An object of this invention therefore, is to provide a building construction utilizing a welded wire stud having adequate strength and resistance to bending and twisting.

Another object of the invention is to provide suitable accessories for use with said stud, in order to facilitate the construction of abuilding; also to improve building constructions in other respects hereinafter specified and claimed.

Referring to the drawings by numerals, the

stud comprises two pairs of spaced chord wires between which zig-zag web wires 3| extend.

the assembly being spot welded together. at the.-

junctions of the various wires. These studs are: made in difierent lengths to approximately fit,-

different ceiling heightsand for a final adjustment as to length, I provide a special extension member 32 which is slidably mounted on one end .of the-stud. This extension 32 is preferably composed of two pairs of spaced wires 33 which are connected at the bottom by a semi-circular integralwire loop 34 and at the top, wires 33 are bent laterally to form sections 35 which are spot welded together. One of the wires 33 of each pair extends beyond the section 35 and is bent at right angles to form a wire section 38, said sections 36 being spot welded together. The composite extension structure is thus substantially U-shaped and is arranged to slide over the end of the stud with webiwires 3| extending between wires 33, loops encircling thechord wires 30, and wires 33 extending inside of chord wires 30. The ex tension is so proportioned that sufilcient friction exists between the extension and the stud, that it is unnecessary to wire the extension in place on the stud. A U-shaped channel runner 38 receives thebottoms of a series of studs between upstanding flanges 39 having spaced perforations 40. A similar channel strip 42 is secured to the ceiling of a room and has downwardly extending flanges 43 to receive the upper ends of extension members 32. Wires 44 attach the extension members 32 to channel flanges 43. A

transverse wire 441115 welded between chord wires 30 at a short distance from the bottom of the stud and a wire 45 passes about wire 44 to attach the lower end of thestud toflanges 39. Perforations 46 are provided in the webs of channels 38 and 42 for receiving nails to attach said channels In order to attach laster bases, such as expanded metal lath 48 to the studs, I provide a clip 49 which is approximately S-shaped, having a central section 58 and legs 5| and 52. The chord wires snap in place between section 58 and leg 5|, being held in place by V-shaped beads 52a and 53 formed in the leg 5| and section 58, respectively. A metallic pencil rod 54 is attached to the leg 52 by a wire 55, being held in place by notches 59 formed in the edge of said leg 52. A coating of plaster 5!v may then be applied to the lath 48 to form a finished wall. The clip leg 52 has a certain degree of resiliency so as to impart substantial sound insulating qualities to the finished wall.

It is often desirable to pass ducts 59 through the wall, Figs. 12, 13 and 14, for the purpose of ventilating and heating. In such a case, I provide splicing members 58 which consist of pairs of spaced wires welded together at their ends. The chord wires 38 are severed at the desired point, the cut ends of the stud are separatedthe required distance, and wires 52 are then used to attach the splicers 68 to the chord wires 38. If

desired, splicer members 63 (Figs. 2 and 3) may be provided in which one end of the splicer members 63 may be secured by welds 64 to the chord wires 98 at one end, and the other end of said splicer member 63 are attached by wires 65 to a second section of the stud wires 38 at the desired distance. In this form of structure, the section of the stud secured by welds 64 together with the splicers 63, become in effect, an extension member and may be sold as such in varying lengths to suit job conditions.

In the form of partition shown in Fig. 9, plaster boards 61 are used as a plaster base for supportmeans as shown in Figs. 10 and 11 in which a U-shaped strap I3 spans the width of the stud, and has downwardly extending legs I4 which engage over opposite clips 69 and the edges of boards 61 to maintain said clips and boards in position against the chord wires 38. The straps I3 are simply dropped in position over the clips 69 at the time of erection and are held flrmly in position by the next succeeding boards.

In erecting a finished partition as shown in Figs. 9, 10 and 11, I attach base boards 15 to nailing strips I6, sa'idstrips being secured by nails 11 to a nailing block I8. The block I8 extends across the web wire IN and is secured thereto by staples 19.

In Fig. 15 is shown the manner of assembling a wooden door buck 8I in a partition in combination with my improved studs. The runner track 38 is fastened around the periphery of thedoor buck with flanges clipped at the corners..

Sections 82 of studs are wired at the bottom to the runner track 38 and at the top to runner track 42. Picture mould 83 is then wired to the studs 82 and various ground strips li'and 84 may 99 by clipping the flanges at the comers and wiring the flanges to studs 9|. In the construction of stairways and the like, channels 92 may to said flange.

be wired to the chord wires 38. Wooden blocks 93 may then be secured between the channels 82 by nails 94 and the handrail brackets may be secured to the blocks 93 by screws or the like.

When it becomes necessary to cut a stud over doors or openings, (Fig. 19) chord wires 38 may be bent inwardly at the bottom to form sections 95, and wires 91 engage over said sections 98 to attach the studs to runner flanges 39. Wires 98 extend diagonally over one of the chord wires 3| and engage a runner flange 39 to urge the stud downwardly against the runner 38. When it becomes necessary to attach heavy fixtures, such as lavatories, etc. to the studs, (Figs. 20 and 21) spaced channels I88 are wired to'the inside of chord wires 38 and blocks I8I are secured between said channels I88 by nails I 82. Bolts III are then passed through the channels I88 and through angles I84 which support the heavy fixture.

In the modified form of construction shown in Fig. 22 a stud is shown which automatically attaches to runner tracks 38 and 42 at top and bottom, without the use of tie wires, thus effecting a marked saving in erection costs. Chord wires I85 .and I86 are arranged at their lower ends to straddle one of the runner flanges 39. Chord wire I 85 is formed into an arcuate snap or latch I81 which engages in one of the flange perfora tions 48 to lock the stud to said flange. An extension member I88 is used at the top of the stud, this member I88 being similar to that shown in Figs. 4 and 5 except that an arcuate snap I89 is provided on chord wire I85 to engage in one of the flange perforations 48 and lock said extension If desired a form of wireless attachment as shown in Fig. 23 may be used. Here a runner track III is used which has flanges II! without perforations. Stud chord wires III straddle the flange H2 and deform said flange slightly so as to prevent movement of said stud I I3 longitudinally of said runner I I I.

I would state in conclusion that, while the illustrated examples constitute practical embodiments of my invention, I do. not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.
